I did'nt find this game in the game forum. I'm copying the rules from another forum:

OK. So the rules are quite simple: the person who's "it" will think of an anime character, and then everyone else's job will be to ask a question that will result in a yes or no answer. Once someone guesses right, that person will be "it" and and he/she will think of a character (you can let someone else be it if you want to though)
Example:
does the person have a blond hair??
- yes
is he a ninja?
-yes
is he a bad guy?
-no
is it naruto uzumaki?
yes

Also, organize and list your answers so people will know whats right and wrong(example below)

YES
ninja
blond hair

NO
Bad guy

P.S. Questions like "Is he a black haired male protagonist surrounded by girls in the alternative life?" are not allowed. You have to ask only thing, for instance "Is that person male?" "Is he/she a protagonist" "Is the action in the alternative life" and etc.
P.S.2. Questions about airing dates should be answered by the 1st season, unless a person wants an answer about specific season.
P.S.3. Season word means - prequels/sequels, not as Fall, Winter, Spring and Summer.
P.S.4. Natural hair colors - Redhead (red/orange), Whitehead (white/gray/silver), Brown (chestnut), Black, Blonde (yellow).

Well let the game begin.
Oh, I forgot to mention, you're only allowed to ask once until the person who's "it" has updated his list, but any amount of people can ask between his posts.
